Abstract Details


To report the outcomes of Keraring implants combined with corneal cross linking in the management of keratoconus.


Eye Laser and Cataract Centre, Cape Town - Private Practice


This is a retrospective review of 27 eyes with IntraLase® FS 150 kHz (AMO) assisted Keraring implantation by the same surgeon, that was followed by epi-off corneal cross linking after six weeks. Visual acuity, spherical equivalent and Oculus Pentacam® scans were obtained and compared at pre-intervention(s) and at least six month’s post-operatively.


89% of participants showed an improvement in UCVA and 82% had a better post operative BSCVA. , There was an average reduction on 1.19 D of myopic spherical equivalent, and 1.78 D reduction in total corneal cylinder. The Steepest K-value had an average of 2.9 flattening. In this study, eyes that showed the best visual improvement, also had the most reduction in KMax and Total Deviation values.


Corneal ring segments and cross linking provide a viable and less invasive option in treating Keratoconus. Patient satisfaction was high. The need for keratoplasty can be delayed or eliminated by such interventions.
